Channel separation/crosstalk  --  Signal from one channel appears in the other owing to mechanical (record players) and inductive coupling. The figure indicates the amount of attenuation in the opposite channel at 1 KHz. in record players, separation is about 6 dB less at 10 kHz, and falls also in the bass. Poor separation blurs the stereo image. Normal range for a turntable cartridge is 20-35 dB.
